TO ALL WHOM IT MY CONGERN:

Be it known that I, CHARLES LnWANno, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in llluminatcd Signs; and I do herebyr declare that the following is a full and exact 'description thereof, refcrencehcing had to the accompanying drawings, and to the letters-of reference marked thereon. I I y The n'ature of my invention consists in combining with a sign, the letters of which are made by perforations in some opaque or semi-opaque material, a movable semi-transparent and parti-colored band; the band and sign are so arranged that light shining through the band will exhibit the perforated letters ina varie-ty of colors, which are constantly changing. v l

` To enableothers skilled in the art'to make and use myinvention, 'I will proceed to describe its construction and use. In the drawings- Figure 1 represents an elevation ofthe sign.

'Figure 2 is a horizontal section of the same. v v y A represents any convenient casin'g for a sign, into which is set a plate of opaque or semi-opaque material. The letters are made in the plate D by cutting out their formsas represented ing. 1. If desirable, D may be an ordinary stencil-plate,cut'with letters and ornaments. B B are two rollers or revolving cylinders, about which a band, C C, revolves. This band C C is made of transparent parti-colored material, so that it passes behind the perforations in D. A light shining through it will exhibit the letters in constantly-varying colors. This band may be propelled by turning the crank H, vor it may be operated by anyconvenient elock-work.

` Having thus described my invention, I will now proceed to set forth my claim.

What I claim as my invention, and desire to secure by'Letters Patent, is

An illuminated sign, made by combining with the perforated plate D a traversing parti-colored semitransparent band, C C, through which the light for illumination passes, substantially as described, and for the purpose set forth.

. CHARLES LEWANDO.
